As I was talking to one of my friends, I said this sentence.
We will need two of it.
I said it looking at the only glass cup I had. I was preparing for the party.
Two of it struck me as extremely wrong. But I knew that I couldn't say "two of these" as there was only one cup in the whole house.
I searched for similar texts but attained no satisfactory results.
I think "two more of it" or "two more of that" is better sounding, but not so sure as to the gramar aspect of it.
Is it grammatical to say "two of it" or "two more of it"?
